The ClearlyDefined project aims to address this challenge by inviting developers across different organizations to crowdsource a global database of licensing metadata for every software component ever published. The issue of unlicensed components is a community-wide challenge that needs a community-wide approach. Additionally, it helps developers to keep track of components that might have vulnerabilities. It not only facilitates collaboration but also ensures legal compliance and protects the intellectual property of contributors. Developers, organizations, and the community at large benefit from clear and standardized licensing. The Need for Clarity and StandardizationĪddressing the issue of unlicensed components is crucial for the continued health of the Open Source community. The Challenge of Unlicensed Componentsĭespite the prevalence of well-established licenses, a concerning revelation emerges from the ClearlyDefined dataset – a substantial percentage of Open Source components lack a designated license or carry the SPDX identifier “NOASSERTION.” This ambiguity introduces uncertainty about the permissible use of such components, potentially hindering collaboration, creating legal complexities, and security concerns for developers. The GNU General Public License ( GPL), embodying the ethos of free software, enjoys a presence but falls behind MIT and Apache 2.0. BSD licenses, both 3-Clause and 2-Clause, maintain a steady but comparatively lower adoption rate. The ISC license, with its simplicity and permissiveness, finds its niche in the JavaScript community. For instance, the JavaScript community often leans towards the MIT license, while Python developers show a similar affinity for Apache 2.0. Each programming language has its own set of license preferences within their ecosystems. The license terrain is not uniform across all package managers. The simplicity of these licenses, allowing users to modify and distribute code with minimal restrictions without imposing additional requirements, has undoubtedly contributed to their widespread adoption. Overall, MIT and Apache 2.0 are by far the most popular licenses, although popularity of licenses vary greatly depending on the package manager. ClearlyDefined is a collaborative project providing comprehensive and standardized metadata about software components’ origins and licenses, its data shed light on the prevailing trends that shape the Open Source ecosystem. Using data from OSI’s community project ClearlyDefined, Aleksandrs Volodjkins explored the ClearlyDefined dataset from September 21, 2023. While many developers know that Open Source software forms the backbone of modern development, the data shows that much of their software is shared (and most likely also used) without a license. The 2023 report of the licenses in use by the biggest package managers highlights the need to educate developers on the importance of licensing information.
